Topeak TUBI 18 – 18-Function Multi-Tool with Integrated Tubeless Tyre Repair System
Experience professional tubeless tyre repair capability combined with comprehensive maintenance functions in the Topeak TUBI 18, an 18-function forged aluminium multi-tool featuring integrated tubeless repair tools, storage compartment for 3.5mm repair plugs, and innovative air-stop technology. This pro-quality precision tool combines chrome vanadium steel hex wrenches (2/2.5/3/4/5/6mm), Torx® wrenches (T10/T25), Phillips #2 screwdriver, stainless steel 2-in-1 tyre reamer/plug insertion tool, serrated knife/saw, tool stop, and detachable air-stop cover—all in a compact 7.6 x 4.1 x 1.8cm package weighing just 119g. The streamlined design stores tubeless repair tools and five 3.5mm x 5cm tyre repair plugs inside the tool body, whilst the tool lock system ensures safe blade and reamer storage. Perfect for road, gravel, and mountain bike tubeless setups requiring trail-side puncture repair capability.
Integrated Tubeless Tyre Repair System – Complete Puncture Solution
The TUBI 18 revolutionises trail-side tubeless tyre repair by integrating all essential puncture repair components into a single compact multi-tool. Unlike carrying separate tubeless repair kits alongside standard multi-tools, the TUBI 18 consolidates everything needed for comprehensive tubeless puncture repairs whilst maintaining full multi-tool functionality for general bike maintenance.
Complete Tubeless Repair Components:
1. Stainless Steel 2-in-1 Tyre Reamer/Plug Insertion Tool
The professional-grade reamer/insertion tool features dual functionality in one robust stainless steel implement. The reamer end expands and cleans the puncture hole, preparing it for plug insertion by creating optimal plug retention dimensions. The 3.5mm plug insertion end features a split-eye design that securely holds repair plugs during insertion whilst releasing cleanly once the plug is seated. The stainless steel construction resists corrosion from sealant exposure and provides the rigidity needed for forcing plugs through tough tyre casings.
2. Detachable Air-Stop Tool
The innovative air-stop tool represents a game-changing feature for tubeless repairs. This small detachable component inserts into the puncture hole after reaming, temporarily sealing the hole to prevent pressure loss whilst you prepare and insert the repair plug. Without an air-stop, tubeless tyres often deflate completely during the repair process, making plug insertion difficult as the tyre bead unseats and the hole becomes harder to locate. The air-stop maintains enough pressure to keep the tyre inflated and the puncture visible, dramatically simplifying the repair process—especially valuable for side-wall punctures or larger holes that leak rapidly.
3. Tool Stop
The tool stop is a simple yet essential component that assists with plug removal after insertion. When removing the insertion tool from a freshly-seated plug, there’s risk of accidentally pulling the plug back out. The tool stop prevents this by holding the plug in place whilst you withdraw the insertion tool, ensuring the plug stays properly seated in the tyre casing.
4. Integrated Storage Compartment
The TUBI 18’s body features a dedicated storage compartment that houses five 3.5mm x 5cm tyre repair plugs, the tool stop, and air-stop tool. This integrated storage eliminates the need to carry separate tubeless repair kits that can be lost, damaged, or forgotten. The compartment keeps plugs clean, dry, and protected from contamination whilst maintaining the tool’s streamlined profile—no external pouches or bulky attachments.
5. Serrated Knife/Saw
The integrated serrated blade serves dual purposes: trimming excess plug material flush with the tyre surface after repair, and general trail-side cutting tasks (cable housing trimming, packaging opening, cord cutting). The serrated edge provides aggressive cutting action even with blunt edge pressure, whilst the locking mechanism ensures safe storage when not in use.
18-Function Comprehensive Tool Coverage
Beyond tubeless repair capability, the TUBI 18 provides extensive multi-tool functionality for general bike maintenance and adjustments:
Standard Multi-Tool Functions:
Hex Wrenches: 2mm, 2.5mm, 3mm, 4mm, 5mm, 6mm (folding design)
Torx® Wrenches: T10, T25 (for disc brake rotors, chainring bolts)
Phillips Screwdriver: #2 (for derailleurs, racks, accessories)
Tubeless-Specific Functions:
2-in-1 Tyre Reamer/Plug Insertion Tool: Stainless steel construction
Tool Stop: Prevents plug removal during tool extraction
Serrated Knife/Saw: Plug trimming and general cutting
Air-Stop Tool: Maintains pressure during repair
Tool Lock: Secures knife blade and reamer for safe storage
Total: 18 integrated functions covering maintenance, adjustment, and tubeless repair
This comprehensive coverage means the TUBI 18 handles brake adjustments, derailleur tuning, accessory mounting, disc rotor servicing, and tubeless puncture repairs—essentially everything needed for trail-side self-sufficiency.
Forged Aluminium Body – Professional-Grade Construction
The TUBI 18’s body is precision-forged from aluminium alloy, providing exceptional strength-to-weight ratio with excellent rigidity. Forged construction (shaping metal under high pressure whilst hot) creates denser, stronger material compared to cast or machined alternatives. This manufacturing process results in superior durability, resistance to impact damage, and long-term dimensional stability.
Forged Aluminium Advantages:
Superior Strength: Withstands significant torque and impact without deformation
Lightweight Construction: Aluminium density optimises weight whilst maintaining rigidity
Corrosion Resistance: Natural oxide layer protects against rust and weathering
Thermal Stability: Maintains dimensions across temperature ranges
Professional Durability: Workshop-quality construction in portable form
At 119g total weight, the forged aluminium body contributes minimal bulk whilst providing the structural integrity needed for high-torque applications and aggressive tubeless plug insertion.
Chrome Vanadium Steel Tools – Workshop-Quality Materials
All hex wrenches, Torx® drivers, and screwdriver bits are precision-manufactured from chrome vanadium steel—the professional workshop tool material standard. Chrome vanadium steel offers superior hardness, wear resistance, and torque capability compared to cheaper stainless or carbon steel alternatives found in budget multi-tools.
The stainless steel tubeless reamer/insertion tool resists corrosion from constant sealant exposure whilst maintaining the sharp cutting edges and rigid strength needed for effective puncture preparation and plug insertion. This material choice ensures long-term reliability even with frequent tubeless repairs in harsh trail conditions.
Tool Lock Safety System – Secure Blade Storage
The integrated tool lock mechanism secures both the serrated knife blade and the tyre reamer/plug insertion tool when folded, preventing accidental deployment during transport or handling. This safety feature eliminates the risk of blade-related injuries when reaching into bags or pockets, whilst also protecting the blade edge from damage during storage.
The lock engages positively when tools are folded, requiring deliberate action to release—you won’t experience accidental opening during riding or transport. When deployed, the tools lock firmly in the open position for safe, controlled use without fear of unexpected closure during operation.
Extendable Design for Leverage – Enhanced Torque Capability
The TUBI 18 features an extendable design that provides additional leverage for high-torque applications. When folded, the compact dimensions suit pocket or bag carry; when extended, the additional length creates better mechanical advantage for stubborn bolts, tight fasteners, or forceful plug insertion through stiff tyre casings.
This extendable functionality particularly benefits tubeless plug insertion, where significant force is often required to push the reamer or insertion tool through tough tyre sidewalls or multiple casing layers. The extended configuration distributes force more comfortably across your hand whilst providing the leverage needed to complete repairs successfully.
Compact Storage Dimensions – Ultra-Portable Carry
Dimensions: 7.6 x 4.1 x 1.8 cm (3″ x 1.6″ x 0.7″) Weight: 119g (4.20 oz)
Despite integrating comprehensive tubeless repair capability, the TUBI 18 maintains remarkably compact dimensions suitable for jersey pocket, saddle bag, or frame bag carry. The 7.6cm length and 1.8cm thickness create minimal bulk, whilst the 119g weight adds negligible load to your riding kit.
The streamlined profile—achieved by storing tubeless components internally rather than as external attachments—prevents snagging on clothing or bag contents. You’ll barely notice you’re carrying comprehensive tubeless repair capability until you need it.
